No Brian,
Wasn't a milling issue, I used purpose written software for that and
never had any issues with the milling. It was some form of a goofy error.
Something like the errant arcs we are talking about. Whatever it was I couldn't
get it to go away and finally stumbled onto turning off the software arcs.

Brad,
Did need to do a milling of the PCB? I do know that true ARCs used to
be prefered for the way some of the older milling software which needed to
interperet out an extra smooth outline for the cutter.

Leo,
No the simple clearance issue is not what I had run into. It's been a while
so it is bugging me trying to remember precisely what did occur with the
software arcs enabled that had me turn them off from then on.

In a nutshell: they mess up your clearance. Start and endpoints of
the individual segments are OK because they sit on the true arc but
the line segments in between violate your clearance, literally by
cutting corners.....
